ADJUSTMENT STEP 3
Test Safety Reverse System
PROCEDURE: Place a 25mm obstacle on the floor
under the garage door. Operate door in DOWN
direction. The door MUST reverse on the
obstruction.
If the door STOPS on the obstruction, it is not
traveling far enough in the DOWN direction.
Increase the DOWN limit by turning DOWN limit
adjustment screw counterclockwise 1/4 turn.
REPEAT TEST.
NOTE: Make sure limit adjustments do not force
the door arm beyond a straight up and down
position. See the illustration on Page 18.
When the door reverses on the 25mm obstacle,
remove the obstruction and run the opener through
3 or 4 complete travel cycles to test the adjustment.
Door MUST NOT reverse in closed position. Repeat
Adjustment Steps 1, 2 and 3 if necessary.

THE PROTECTOR SYSTEM™ PROVIDES AN
ADDITIONAL MEASURE OF SAFETY AGAINST A

an obstruction, causes a closing door to open and
prevents an open door from closing. STRONGLY
RECOMMENDED FOR HOMEOWNERS WITH SMALL
CHILDREN.
